So many 40 year old chicks are divorced. Maybe 50%. They usually get the house in the divorce, half the savings, the best car and alimony/child support. They are getting into their sexual most horny period in their life. That's what a 40 year old chick has to offer.
Most of them have kids, that's a serious problem
Like which 18-40 year old does NOT have kids these days...? Most girls in their twenties all have kids...
